first example embodiment

[0035]FIG. 1 is a block diagram conceptually illustrating an anti-malware system 1 according to a first example embodiment of the present invention. The anti-malware system 1 according to this example embodiment roughly includes an anti-malware device 10, a terminal device 20, a live sandbox server device 30, and a communication network 40. The anti-malware device 10, the terminal device 20, and the live sandbox server device 30 are connected via a communication network 40 in such a manner as to be able to communicate with each other. Note that the direction of each arrow in block diagrams of FIG. 1 and the like of the present invention is illustrated by way of example only, and is not intended to limit the direction of signals between blocks.

[0036]The terminal device 20 is an information processing device including a processor and a storage device (not illustrated) and is capable of executing software 200 which is externally obtained via the communication network 40. When the anti-...

second example embodiment

[0077]FIG. 8 is a block diagram conceptually illustrating a configuration of an anti-malware device 50 according to a second example embodiment.

[0078]The anti-malware device 50 according to this example embodiment includes a storage unit 51, a subject attribution collection unit 53, an object attribution collection unit 54, and a determination unit 55.

[0079]The storage unit 51 stores risk information 510. The risk information 510 is information in which there are associated the value indicating the attribution of an information processing device 60 that executes software 600, the value indicating the attribution of the software 600, and the value that depends on the attribution of the information processing device 60 and the attribution of the software 600 and that indicates the degree of risk when the software 600 is executed by the information processing device 60.

[0080]The subject attribution collection unit 53 collects the value indicating the attribution of the information proc...

Abstract

An anti-malware device 50 includes: a risk information storage unit 51 in which risk information 510 is stored, in which there are associated a value indicating an attribution of an information processing device 60 for executing software 600, a value indicating an attribution of the software 600, and a value that indicates the degree of risk when the software 600 is executed; a subject attribution collection unit 53 for collecting the value indicating the attribution of the information processing device 60; an object attribution collection unit 54 for collecting the value indicating the attribution of the software 600; and a determination unit 55 for determining that the software 600 is malware when the value indicating the degree of risk obtained by comparing the risk information 510 and the values collected by the subject attribution collection unit 53 and object attribution collection unit 54 satisfies a criterion.

Description

TECHNICAL FIELD[0001]The present invention relates to an anti-malware device and the like that detect malware and take a countermeasure against the malware.BACKGROUND ART[0002]In recent years, a threat to security due to malicious software (hereinafter referred to as malware) that provides a computer with an unauthorized command has been a social issue. Accordingly, expectations have been raised for a technique for accurately detecting malware getting into a computer so as to eliminate such a threat to security.[0003]As an example of a technique related to the above-mentioned technique, PTL 1 discloses a malware analysis system that receives a malware candidate sample from a firewall, and automatically generates a signature code when it is determined that the sample is malware. This system determines whether or not the malware candidate sample is malware by using various heuristic methods.CITATION LISTPatent Literature[PTL 1] Japanese Translation of PCT International Application Pub...
